Description
LiYA 225 Efficient 2-Channel Power Distribution
First and foremost, the LiYA 225 2-Channel Class D Digital Amplifier serves as a powerful, streamlined backbone for modern distributed audio networks. Whether you want to upgrade a dedicated residential media room, a corporate boardroom, or a multi-zone retail venue, this amplifier manages your speaker loads flawlessly. Furthermore, it pairs an advanced digital amplification design with a universal switching power supply. As a result, the system maximizes raw power delivery across both channels while safely minimizing energy consumption. Consequently, you get high-end, continuous performance without worrying about excessive heat buildup in your gear rack.

Hybrid Voltage Architecture & Control
Fortunately, you can completely eliminate the need for bulky and expensive external audio transformers. This is because the LiYA 225 utilizes a unique hybrid architecture that smoothly drives traditional low-impedance speakers (250W x 2 RMS @ 8 ohms). In addition, the exact same unit simultaneously powers long-distance commercial configurations (250W x 2 RMS @ 70V/100V). Therefore, this immense flexibility ensures that your speaker layouts receive crystal-clear, uncompromised power regardless of the installation distance. Moreover, the integrated load transfer switch and dedicated rear volume controls allow you to fine-tune your zones safely during setup.
Flexible Connectivity & Clean Audio Performance
In order to simplify your integration process, we engineered the LiYA 225 with modern digital and analog connectivity in mind. For example, the rear panel easily accommodates standard unbalanced RCA and balanced 3-pole Euroblock inputs. Specifically, you can also leverage the built-in Optical and USB inputs to achieve pristine digital audio playback directly from your source.
Meanwhile, heavy-duty Euroblock terminal blocks manage the outputs to guarantee a stable, signal-loss-free connection to your loudspeaker lines. Because the amplifier maintains an exceptional Signal-to-Noise Ratio (SNR) of ≥ 92dB along with minimal Total Harmonic Distortion (< 0.1%), your music and announcements will always sound immaculate. Ultimately, this means your sound stays beautifully transparent even when pushing the system to higher volume thresholds.
